New Mileage Rules Encourage Small Cars To Become Big Trucks For Lower MPG via @GreenCarReports
I am confused, I thought they already had a solution to this problem. It is two pass approach. In year one, they set targets for each class of vehicles based on footprint and the current mix of sales for that manufacturer. But the manufacturer still must meet the target MPG for that year or risk penalty regardless of the mix of vehicles. However, they will not be penalized if they met the targets for the year. In year two, the EPA readjusts the targets for a given vehicle footprint based on the year one sales mix. So if you sell more larger vehicles, your targets for fuel efficiency will increase for them. The footprint mpgs are only temporary targets, the manufacturer still must reach the target overall CAFE goals.
